NASA’s Chandra X-ray Observatory examined eight open star clusters aged between 45 million and 750 million years, focusing on young Sun-like stars. The study found these stars emit only about a quarter to a third of the X-ray radiation previously expected.

This lower X-ray emission suggests young Sun-like stars are less active in X-rays than assumed, potentially creating a more favorable radiation environment for orbiting planets. This could improve the prospects for life in these stellar systems.

Images of the star clusters Trumpler 3 and NGC 2353, using data from Chandra, PanSTARRS, and NASA collaborators, were released to illustrate the research.
